Let me give you a response from a very honest place : I would never play a game that would require me to share it. It'd see behind this cheap trick and refuse to take part in it. A game has to captivate me, impress me, or have enough aesthetic qualities for me to want to share it with my friends. In other words : if it's good, I will share it anyway.

My advice : make a good game. No need for cheap tricks.

Could not agree more .

Do you know what a variable is ?

there are also many tutorials on variables

What if they chased him only while he was visible , then make him invisible when he is caught , then visible again after a time lag ?

I concur , the same has happened to me , i also have badge's missing .

Every X seconds

Run the event regularly at a given time interval in seconds. This can also be used beneath other conditions to only run the event at a given time interval while the other conditions are true, e.g. "Player is holding spacebar AND every 0.5 seconds: fire laser".

Very entertaining , brought back some memories .

If enemies.x < player.x , enemies.x=enemies.x+1 else enemies.x=enemies.x-1

if distance(enemies.x,enemies.y,players.x,players,y) < whatever then action whatever .

Do you know what a thousand lawyers at the bottom of a lake is.....................................a good start !

Local variables

Local variables are variables placed nested under other events, or inside a group. They also show with a different icon to global variables.

A local variable.

The main difference between global and local variables is local variables can only be accessed in their scope. A local variable's scope is its level of sub-events. All other events at the same level of indentation, or lower levels, can access the local variable. Events above it (less indented) cannot access the local variable.

For example, if an event variable is in a group of events, it becomes a local variable. Then, it will only appear as an option for a variable in events inside that group. In other groups or in other event sheets it does not appear at all and cannot be accessed. This makes the variable local to the scope in which it is placed.

Local variables convenient for temporarily holding variables over a short range of events, such as to calculate an average value (where a temporary 'sum' variable may be necessary). It also helps keep the project simple, since it prevents the need to create more global variables, which appear everywhere in the project even if they are not needed everywhere.

The scope of local variables is designed to mimic how the scope of variables works in real programming languages.
